Hi everyone,
After upgrading to Proxmox VE 8.4.1, I started experiencing intermittent connectivity issues with the eno1 interface, which uses the e1000e driver.
The interface is part of vmbr0, and although the physical link stays up, the host becomes unreachable on the network after a few days of uptime. A reboot is the only way to restore connectivity.
Here’s what I’ve tried so far:
Thanks in advance for any insights!

Here’s what I’ve tried so far:
- Disabled tso, gso, rx, tx, sg, rxvlan, and txvlan using ethtool
- Added those settings to /etc/network/interfaces using a post-up command
- After applying these changes, the issue hasn’t occurred again (so far), but I'm not sure if it's fully resolved
- Has anyone else experienced this kind of issue with the e1000e driver on Proxmox 8.4.1?
- Is this a known bug or something the Proxmox team is already aware of?
- Is it safe to permanently disable all these offload features for production use?
Thanks in advance for any insights!
